SAWMILL SET-WORKS.

SPECIFICATION forming part of Letters Patent No. 764,484, dated July 5,1904.

Application filed March 14, 1903. Serial lie-147,828. (No model.)

To all whom it may concern:

Be it known that I, EDWIN C. MoNnon, a citizen of the United States,residing at Liberty, in the county of Sullivan and State of New York,have invented new and useful Improvements in Sawmill Set-VVorks, ofwhich the following is a specification.

My invention has relation to improvements in sawmill set-works; and theobject is to improve and simplify the existing art by providing amechanism for setting the log in its relation to the saw which is simplein construction, accurate in the operation and results, and durable inthe uses to which it is adapted.

The invention embodies an operating-wheel having indications of spacesfor log movements thereon, a lever to actuate the wheel, measurementspredetermined to indicate the scope of the lever movements, and meansfor restoring the setting mechanism to initial position.

The invention consists in the novel construction of parts and theirassemblage or aggroupment in operative combination, all as will behereinafter fully described and the novelty thereof particularly pointedout and distinctly claimed.

It may be prefaced that generally sawmill set-works are provided withratchet wheels with index-pointers of some description opbe seen thatthere cannot be any variation when one wheel does all the work andindicates and announceswith convenience and certainty the predeterminedmovement and, result.

I have fully and clearly'illustrated my invention in the accompanyingdrawings, to be supporting table and the return-wheel which reverses theratchet-wheel and returns it to the initial position. Fig. 3 is a topplan view of the device, showing the lever-table, the lever, andthereversing-gears. Fig. 4 is a plan view of a portion of thesetting-wheel whereon are designated the cube designatirig-blocks anddesignatingdigures to denote themeasurements made by the successiverevolutions of the setting-wheel. Fig. 5 is a plan view of asetting-wheel whereon are mounted cubes having designated numbersindicating the recurring figures to acquaint the sawyer of thesucceeding scales of movement. Fig. 6is a plan view of a setting-wheelhaving successive movements of revolution marked thereon. Fig. 7 is aperspective view of one of the indieating-cubes.

In the drawings similar reference notations appearing in the severalillustrations designatelike parts.

It has not been deemed essential to illustrate the head-blocks andlog-beams nor the knees with which the device is associatedv furtherthan to show the pinion on the lower end of the vertical shaft, whichpinion engages with the rack, which moves the knees on the beam to setthe leg up the required distance. These are all well known, may be ofany approved construction, and constitute no part of my invention.

Referring to the drawings, A designates a vertically-arranged hollowcylindrical column or standard of such dimensions as may be required andhaving a base adapted to be secured to the log-beam in any suitablemanner and by any suitable means. In the cylindrical column is rotatablyarranged a vertical shaft 1, on the lower end of which is lixedlymounted a pinion 2, adapted to engage with the rack on the knee of thecarriage in a well-known manner. The upper end of the vertical shaft 1extends above the end of the hollow column and has keyed to theextending portion the horizontally-arranged setting-wheel 3, consistingof a wheel having a determined number of cogs graduated into segmentalgroups in relation to the pinion and rack, so that a prescribed movementof the setting-wheel will move the log-knee a certain prescribeddistance, as will be more fully specified hereinafter.

From the upper portion of the column A projects a table 4, extending ina horizontal plane parallel with the lower face of the setting-wheel andhaving its outer edge curved concentric to the axis of thesetting-wheel, and on this curved edge is marked a scale 5, representingone-half an inch to two inches, so that by placing the inner face edgeof the lever on a radial line coincident, for instance, to the scorerepresenting one inch and pulling it to the stop the movement will movethesetworks one inch. By this means I dispense with all stop-pinsexceptthe limit-pin 6, which is stationary and may be made integral withthe table.

7 designates a collar secured movably on the column A in line with theupper face of the table, and to this collar is rigidly secured or madeintegral therewith a lever 8, which extends outward beyond the table andconstitutes the means for operating the set-wheel. On this lever ispivotally mounted a pawl 9, which engages the teeth of the set-wheel andturns it with its shaft. To one end of the pawl is secured a rod 10, theouter end of which is suitably connected to the end of a hand-rod 11,which is pivotal-1y mounted on the outer end of the lever 8. Theset-wheel 3 is formed on its under face with a rack 12, with which Tothe column A is fixed a horizontall'y-exwhat is claimed as new istending arm 15, having a bearing formed on its outer end, on which isjournaled the hub of a face-gear wheel 16', which meshes with anidler-pinion 17, journaled on a bearing 18-, formed on or fixed in avertical arm 19, extending from the arm 15, as shown. dle 20 is providedto turn the wheel 16. The purpose of this mechanism is to return theset-wheel with its associated parts to the starting-point.

On the edge of the table 4 is fixed a pointer 21, which indicates to theoperator that the desired point of movement of the set-wheel has beenreached.

On the face of the rim of the set-wheel 3 are formed or secured a seriesof cubes 21, having marked thereon figures designating the tooth of theset-wheel with which the pawl 9 is to be engaged to move the wheel tothe determined point indicating the cut-line for the saw. The sameresult may be accomplished by a ring-plate marked with thetooth-designations; but I prefer the cubes because they present moreconvenient means for visual observation of the required numbers.

To utilize the device after the log has been shaped by cutting off theslabs it is moved up against the faces of the knees. Then supposing itis intended to saw one-inch boards. All that is necessary is to turnwheel 3 so as to place the nose of the pawl 13 in the tooth which liesor is positioned directly under the tooth which designates the width ofthe log, say, sixteen inches, and allowing one-quarter inch for thesaw-cuts or the thickness of the saw.

' Then the pawl 9on the lever would be placed in alinement with thetooth of the setting-wheel bearing the number 14f; and the lever pulledup to the stop 6, thus carrying the knees,with the log, the requisitedistance to make the cut. Then in succession the pawl would be set inthe teeth numbered 13 3-, 12%, 11,

The sawyer can set the log speedily, because he has only the set-wheelto observe, and the setting is attained with absolute accuracy, becausethere is nothing to get outof place, the wheel being fast on itsshaftand the teeth bearing the correct relation at all times. To

expedite the work, after the log has been set and started the pawl maybe placed in thenext proper tooth while the saw is cutting. By havingthe figures arranged asshown and the requisite spaces designated therebyit is not necessary to count the number of teeth toascertain the nextplace for the engagement of Z the pawl.

In the present instances shown in the drawings the set-wheel is intendedas being seventeen inches in diameter and is provided with ninety-sixteeth, so that eight teeth and two teeth for out shoves the log over toproduce a one-inch board. I

Having thus fully described the invention,

1. In a sawmill set-works, a setting-wheel having its perimeter providedwith a determined number of teeth divided into segmental groups, andcubes mounted on the face A hanof the wheel to designate the boundariesof the groups, said cubes having marked thereon figures to designatecorresponding units of advance of the knee by the forward move- I mentof the wheel.

2. In a sawmill set-works, a hollow supporting-column, a Vertical shaftmounted rotatably in the column, a pinion on the lower end of the shaftto engage the knee-rack, a settingwheel mounted on the upper end of theshaft and provided with a determined number of teeth divided intosegmental groups, designations on the wheel indicating boundaries of thel groups, and a comcident circular rack on its responding segmentalgroups, and a stop projecting Vertically therefrom, a lever mounted onthe setting-wheel shaft to move on the plane of the table and lodgeagainst said stop, a pawl on the lover to engage the teeth of thesetwvlleel, whereby when the nose of the pawl engages in a designatedtooth of the wheel it can be moved the distance indicated by thesegmental group, and a pawl 13 to engage the circular rack under thesetting-wheel.
